This is a perfect example of how airfares just baffle the mind.

This is obviously not appropriate to your situation but just used as an example:

Using that same near $700 CLT-SXM route if you START in BOS and connect through CLT (both ways) the fare DROPS to $381 R/T...for the same CLT flight....so with the BOS flight added it's a $300 discount <img src="http://www.traveltalkonline.com/forums/images/graemlins/duh.gif" alt="" />
